Matthew Wade said Brad Haddin remained Australia's number one Test match wicketkeeper despite his own maiden Test century Tuesday shifting the final West Indies Test in favour of the tourists.

Wade, 24, was thrust behind the stumps for this series when 34-year-old Haddin stunned his side by announcing he was returning home for personal reasons and would not be available for selection.

Wade, a promising Aussie Rules footballer in his teenage years when growing up in Tasmania, came in when Australia were tottering on 164-6 in their first innings on the first day on Monday.

While he took time to move to his half century he went on the attack after that and scored his second fifty off just 33 balls with the highlight two successive sixes off the West Indies' most potent bowler Shane Shillingford.

He was eventually out for 106 as Australia were dismissed for 328 on Tuesday and by stumps had the hosts in trouble on 165-8 giving them a lead of 163 and looking set to win the series in which they hold a 1-0 lead.

Wade, who overcame testicular cancer aged 16, refused to get carried away about his innings being the one that sealed his place ahead of Haddin in the Test side.

"There's a lot of one day and T20 cricket in between, a lot of water under the bridge before the first Test against South Africa at the Gabba (in November), so I'll do my job and see how it goes.

"Rodney Marsh (Australian selector) said that 'Hadds' is No. 1 in Test cricket and that sits fine with me, I'm happy to fill the void for a while and go and play some one day cricket."

Wade, whose father Scott played Aussie Rules for the famed Hawthorn club in Melbourne, said that he was not looking too far down the road as regards his long term Test career.

He added that the tour had been a gradual learning process where he had had to adapt to vastly different conditions from those he had encountered before.

"I don't think I had any doubt I could play Test cricket, it's been a massive tour for me, I've learned so much from the first game we played, the one dayers where the conditions were just so different from what I'm used to," he said.

"I felt every game that I was getting a lot better, we've been working on things every day to get better in these conditions, we've got subcontinent conditions coming up at the T20 WC and that kind of stuff.

"It was about improving the little things.The conditions were a massive thing and I brought my sweep shot in. Halfway through the one day series I decided I'd use the sweep a lot more and I've brought that with me into the Tests.

Wade's improvement throughout the tour was saluted by West Indies assistant coach Toby Radford.

"I think he has developed as the whole series has gone on," said Radford.
